ProMED is one of the most useful scientific tools you’ve never heard of. It’s a global surveillance system of infectious disease outbreaks which is available, for free, to researchers and the public alike. But ISID, the society which runs the platform, claim they have run out of money to support ProMED and will be switching to a subscription service, against the wishes of both users and staff. ProMED editor Marjorie Pollak tells Science in Action about the vital service ProMED has played in pandemic monitoring – including the very first COVID outbreaks - and ISID boss Linda MacKinnon considers what’s next for the platform.

From wildfires in Europe to droughts in Africa, we have covered every kind of environmental disaster across most of the globe in the space of the past few weeks. To complete the distressing bucket list of climate extremes, we’re talking to sea ice expert Caroline Holmes on the concerning forecast for Antarctica.

Despite these terrestrial challenges, NASA is still trying to defend Earth against nearby objects which might hit us from space. The Double Asteroid Redirection Test (DART) was launched at the asteroid Dimorphos back in in November 2021 and, a few weeks ago, the Hubble space telescope observed a swarm of boulders shed by Dimorphos post-impact. Some UK newspapers are concerned about their trajectory, but astronomer Dave Jewitt is here to calm us all down.

This week on the show that looks for the science behind the news, Marnie Chesterton investigates mystery after mystery. Where is Yevegeny Prigozhin, the leader of the Wagner Group, and could science help to trace him? Which animals would do best at a game of hide and seek? And we hear about the time when half the stuff in the universe went missing, and how cosmologists found it again.

We continue our endless quest to identify the Coolest Science in the World. This week’s contender studies the murky side of the genome – dark DNA. Plus the low-down on the indefinite doctor’s strike in Nigeria, we look behind the latest news about our warming oceans and have you ever felt someone else’s pain? You might be the 1 in 50 people known as mirror touch synaesthetes.

All that plus your emails, whatsapps and even more fruit chat.

Presented by Marnie Chesterton Produced by Ben Motley, with Margaret Sessa Hawkins, Alex Mansfield, Sophie Ormiston, Katie Tomsett and Florence Thompson.

How do we really get happier? In a new review in the journal Nature Human Behavior, researchers Elizabeth Dunn and Dunigan Folk found that many common strategies for increasing our happiness may not be supported by strong evidence. In today's Short Wave episode, Dunn tells co-host Aaron Scott about changes in the way scientists are conducting research, and how these changes led her team to re-examine previous work in the field of psychology.

The ability to create wrought iron cheaply has been called one of the most significant innovations in the British Industrial Revolution. It's known today as the Cort process, named after British banker Henry Cort, who patented the technique. But Dr. Jenny Bulstrode, a historian at University College London (UCL), found that Cort stole the innovation from 76 Black enslaved ironworkers in Jamaica.

Imagine spending six months of every year living in total shade. That’s what life is like for residents of the Norwegian town of Rjukan, set so low in a valley that they see no direct sunshine at all from October to March.

Marnie Chesterton heads there to hear about an ingenious solution: giant mirrors that beam rays down into the town square, where locals gather to feel the reflected heat.

The man behind the project was motivated by a need for winter sun – but how much difference does it really make to our health and happiness? That’s the question posed by this week’s CrowdScience listener Michael, who has noticed living in the rainy Australian city of Melbourne is taking its toll.

Many pensioners claim sunshine relieves achiness as well as conditions like arthritis but one of the biggest scientific studies found temperature has no real impact on reported pain levels, while factors like air pressure and humidity may play a role.

When it comes to our mood, it seems that spending time outside is more important than feeling the heat. The optimum temperature for wellbeing is around a cool 19 degrees centigrade, while excessive warm weather has been linked to an increase in violence and crime.

Ever felt like you were watching yourself and the rest of the world from outside of your body? Or floating above yourself? Well, scientists finally know what part of your brain is causing that sensation. NPR science correspondent Jon Hamilton shares the tale of the discovery with host Aaron Scott. Plus, they talk about why it may be helpful to occasionally venture outside of your bodily self.

Science in Action returns to H5N1, the fast spreading strain of bird flu which has caused devastation in the sky, sea, and land over the last few months, with no end in sight.

Roland visits Skomer Island and the coast of Wales where sea bird colonies are threatened and hundreds of guillemots have washed ashore dead, struck down by bird flu.

We also hear of outbreaks on Finnish fur farms where controversial plans are in progress for culls of wild birds, of mysterious infections of domestic cats in Poland, and bird flu causing brain swelling in grey seals.

Plus, we get an update on efforts to vaccinate condors in California against the disease.

The World Cup has us looking at why women get more ACL injuries, how to avoid cracking under pressure, and why some animals play dead.

Also on the program we consider the pros and cons of Artificial Intelligence in Africa, whether the continent is turning to nuclear power, and if banana skins are hallucinogenic.

For decades, humans have harvested the blood of horseshoe crabs, which is used to test whether many of our vaccines and medicines are contaminated with harmful bacterial toxins. But the horseshoe crab harvesting industry has few regulations and a lot of secrecy. NPR investigative reporter Chiara Eisner talks to us about expansion of this industry and why synthetic alternatives to the blood aren't being widely used in the United States.
